BUNDLE-EJECTING MECHANISM FOR GRAIN-BINDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 380,901, dated April 10, 1888.

Application filed November 26, 1886. Serial No. 2l9,922. (No model.)

To aZZ whom itmay concern.-

Be it known that I, Mosns A. KELLER, a citizen of the United States, residing at Batavia, in the county of Genesee and State of New York, haveinvented a new and useful Improvement in Bundle-Ej ecting Mechanism for Grain-Binding Machines, of which the following is a speciiication.

My invention relates to improvements in which the bundle-ejecting arms are journaled upon eccentrics secured to the knotter-frame and having said ejecting-arms actuated by revolving cranks secured upon the mainknotter-operating shaft. I obtain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a rear side elevation of the entire binding mechanism with my improve ments. Fig. 2 is an end View with ejecting-arms in position in forcing the bound bundle out of the binding-receptacle. Fig. 3 is a longitudinal sectional view taken on the dotted line w of Fig. 2. Fig. 4 is a side view of the knotteroperating wheel. Fig. 5 is an end view of the ejecting-arm mechanism with the ejecting-arm in the position opposite to that shown in Fig. 2. Fig. 6 shows detail parts of the same.

Similar letters refer to corresponding parts throughout the several drawings, in which- A is the main frame of the entire binding mechanism, and in its upper longitudinal arm is journaled the main knotter-operating shaft B. A. knotter-operating wheel, 0, is affixed to said shaft and is provided with a mortise, K, for actuating the ejecting-arm H. The knotter-frame D is journaled upon the shaft B, between the wheel 0 and ej ecting-arm crank E, which crank is rigidly affixed to the end of the shaft B. The breast-plate N and deck M formthe binding-receptacle.

Rigidly secured upon the end of the upper longitudinal arm of the frame A is an eccentric, F, upon which is j ournaled the ejectingarm H. Said arm is provided with a roller, J, which engages the mortise K of knotter op crating wheel 0. The wheel 0 revolves in the direction of the arrow indicated in Fig. 2. It

will be seen by the several drawings that the true center of the eccentric is below the shaft B and next to the binding receptacle. The motion of the slotted crankF, or that of the slot in wheel 0, is much faster at the outer end than at the end next to the axis of said wheel 0 or crank E. It will therefore be apparent from the position of the eccentrics F and G that the motion of the arms H and I will be much faster as they reach the bindingreceptacle than at the extreme opposite position, and also much faster than if they were rigidly affixed to the shaft 13. Experience in all kinds of grain has proven that the motion of the ejecting-arms is too slow to completely separate the bound bundles in tangled grain, and

it would not be safe to increase the speed of the entire binding mechanism to overcome the defect in the ejecting mechanism; but by my improvements, illustrated in the drawings, I obtain the desired object--namely, that of a quicker action of the ejecting-arms without altering the speed of the entire binding mechanism.

The eccentrics F and G may be made adjustable,so as to locate the quick action of the ejecting-arms at any desired point; but since the quick action is only necessary while the arms pass the side of the binding-receptacle the said eccentrics can be cast to the binder and knotter frames, or otherwise rigidly secured in their place, and thereby simplify the construction.

It is obvious that the mechanism may be altered to accomplish the'same results without departing from the essence of my invention.

What I claim, and desire to secure by Letters Patent, is-

1. The combination, with the stationary binder and knotter frames and knotter-operating shaft, of the stationary eccentrics affixed to said frames, the ejecting-arms journaled upon said eccentrics, andmeans for revolving said arms from the knottenoperating shaft, all

. arranged substantially as described, whereby the arms are given an accelerated motion as they strike the bundle.

2. The combination, with the stationary ec-- centrics and knotter operating shaft, of the revolving bundle-ejecting arms journaled upon said eccentrics, the rollers journaled to the arms, and the slotted cranks on the shaft for operating the ejecting-arms, as set forth.

3. The combination, with the stationary binder and knotter frames and knot-ter-operat ing shaft, of the stationary eccentrics affixed one secured to the frame A and one to the to said frames, the ejecting-arms journaled upon the eccentrics, and the slotted knotteroperating wheel and slotted crank ,on the 5 knotter-operating shaft, and connecting n1echanism for revolving said ejecting-arms more rapidly as the same strike the bundle, as set forth.

4. The improved bundle-ejecting mechanro ism, composed of two stationary eccentrics,

knotter-frame D, and having journaled upon said eccentrics two revolving ejecting-arms, H and I, operated by and in conjunction with two slotted revolving cranks, E and O, actuated [5 by the knottcr-operating shaft B.
